Let G=(V,E) be a directed graph and let P be a shortest path from s to t in G. In the replacement paths problem we are required to find, for every edge e on P, a shortest path from s to t in G that avoids e. We present the first...
The linear-time shortest path algorithm for acyclic graphs can be found in Lawler (1976). Using lower bound to prune search goes back to the late 1950s, where branch-and-bound search was proposed. The first use of distance goal estimates to guide state space search is probably due to ...

The rest of the paper is organized as follows: in Section 2 we formally define the shortest path query problem, as well as kNN problem over weighted graphs. In Section 3 we introduce the formal definitions of the tree decomposition and prove the theoretical results regarding the shortest path ...
